With over 140,000 device models , it covers everything from low-voltage breakers and fuses to solar panels and protective relays.
The library is divided into distinct categories covering the entire electrical infrastructure:
The core function of the ETAP Library is to serve as an extensive, validated database of electrical equipment. It contains thousands of pre-modeled components, including synchronous generators, transformers, transmission lines, protective relays, circuit breakers, and variable frequency drives. However, what distinguishes this library from a generic parts list is its adherence to industry standards (e.g., IEC, ANSI, NEMA). Each component is not merely an icon; it is a mathematical model pre-loaded with characteristic curves—saturation curves for transformers, torque-speed curves for motors, and time-current curves for protective devices. etap library
Consider a data center’s microgrid. The library contains models of diesel generators, photovoltaic inverters, and battery storage systems. As real-time data streams in (fuel levels, solar irradiance, state of charge), the ETAP engine re-parameterizes the library models on the fly. This allows operators to run "what-if" scenarios: If we lose one utility feeder, can the library-modeled generator start and synchronize within 10 seconds? The fidelity of the answer depends entirely on how accurately the library reflects the dynamic behavior of the actual equipment.
Standard winding impedances, X/R ratios, and thermal damage curves. Motors and Generators: Subtransient ( Xd′′cap X sub d double prime ), transient ( Xd′cap X sub d prime ), and synchronous ( Xdcap X sub d ) reactances, alongside inertia constants ( ) for dynamic simulations.

The most significant value proposition of the ETAP Library is its commitment to quality through Verification and Validation (V&V). This is not a one-time event but a continuous process that underpins every release. The V&V process includes:
Both meanings, in their respective fields, represent a move toward greater efficiency, standardization, and power—whether that's the flow of electrons or the logic of code.
Data is based on recognized standards (IEEE, IEC, ANSI).
